Foreign Relations

Little more than a year after U.S. spy agencies concluded that Iran had halted work on a nuclear weapon, the Obama administration has made it clear that it believes there is no question that Tehran is seeking the bomb. In his news conference this week, President Obama went so far as to describe Iran's "development of a nuclear weapon" before correcting himself to refer to its "pursuit" of weapons capability. Obama's nominee to serve as CIA director, Leon E. Panetta, left little doubt about his view last week when he testified on Capitol Hill.

The last time Indonesia allowed Peace Corps volunteers to work here, they weren't sent into villages to teach English or build schools. The Americans were assigned to whip athletes into shape for the 1964 Olympics. The peculiar aid to reluctant hosts didn't work out: Jakarta ended up boycotting the Tokyo Games, and thugs from the Indonesian Communist Party, which accused the American coaches of being CIA agents, ran them out of the country in 1965, less than three years after they had arrived.

Airline flights. Phone service. Money transfers. Those are among enticing new or expanded business opportunities seen ahead for U.S. companies with Monday's loosening of the U.S. embargo with Cuba. "This is a big deal; it's a significant change in U.S. policy," said former Ambassador David A. Gross, the U.S. coordinator for international communications and information policy and a partner at law firm Wiley Rein.

The road to Bala Baluk district stretches arrow-straight ahead, with heat-shimmered cucumber fields on either side. But determining exactly what transpired nearly two weeks ago in a hamlet called Garani takes a far more twisted path. A battle raged. Bombs fell. Afghan officials say at least 140 civilians died, two-thirds of them children and teenagers, in what may prove the most lethal episode of civilian casualties since the U.S.-led invasion of Afghanistan in 2001. Days of interviews with U.S.

The Obama administration announced Monday that it would permit unlimited travel to Cuba by Cuban Americans and lift limits on transfers of money to relatives on the Caribbean island while keeping in place many long-standing U.S. trade restrictions. Obama's moves make good on a campaign promise and seek to take advantage of shifting winds in Havana as Raul Castro, who formally took over from his ailing brother Fidel a year ago, adopts limited reforms.

The young man named Anton is a member of Russia's "lost generation." He's the son of middle-class, college-educated engineers; he studied at a good university and became a truck sales manager in Moscow. He's also a 28-year-old heroin addict. In the years since the U.S.-led invasion of Afghanistan triggered a sharp increase in poppy cultivation, Russia has been flooded with heroin. The dope has crept along a drug trail stretching from Afghanistan through Tajikistan and other Central Asian nations and over the Russian border, turning this country into the world's top consumer of heroin, the government says.

Secretary of State Hillary Rodham Clinton warned Wednesday that the United States may erect a "defense umbrella" over the Middle East if Tehran continues its nuclear program, a sign that the Obama administration is preparing for the reality of an Iranian bomb.

George J. Mitchell, the new U.S. envoy to the Middle East, arrived in Israel on Wednesday to begin testing his axiom that there's no such thing as a conflict that cannot be ended. Yet even as Israeli and Palestinian leaders offered ideas on how the Obama administration can help bring about peace, the prevailing mood on both sides was that their decades-old fight had become almost hopelessly deadlocked.

The "Do Not Cross" line here between North and South Korea has a prosaic feel to it: a concrete speed bump. The almost imperceptible hump, sitting between two blue buildings that straddle the 38th parallel, would look at home on a suburban street. Likewise, the swath of grass and concrete of the Joint Security Area resembles a college campus -- uncommonly quiet and devoid of students -- more than a hyper-guarded demilitarized zone. But hyper-guarded it is.

In asserting that Beijing is "manipulating" its currency, U.S. Treasury secretary nominee Timothy Geithner raised the hopes of some American politicians and business groups that have long pressed for tougher action against China. But the reality is that the Obama administration might have even less leverage than the Bush team to persuade the Chinese on the currency and other economic issues, at least for now.
